Description

Technical Field

[0001] The utility model belongs to the technical field of tire molds, and particularly relates to an assembled tire mold. Background Art

[0002] Molds for vulcanizing and molding various tires. Tire mold classification: split molds, which are composed of a pattern ring, a mold sleeve, and upper and lower side plates. Split molds are divided into conical surface-guided split molds and inclined plane-guided split molds: two-half molds, which are composed of an upper mold and a lower mold.

[0003] In the existing tire processing technology, the tire blank is first placed in a mold heated to about 180 degrees. The tire blank is pressed against the tire side plate and the tread block by inflating the forming capsule. The gas between the tire blank and the inner wall of the mold cavity is squeezed by the tire blank and is passively discharged from the exhaust holes of the tire side plate and the tread block, so that the tire blank can fill the cavity, and the tire blank starts to vulcanize until the vulcanization is completed. When the pattern on the outer side of the tire needs to be adjusted, the tread block on the mold side plate needs to be removed and replaced with the required tread block. Since the tread block and the mold side plate are fixedly connected by a plurality of bolts, during the process of replacing the tread block, the disassembly and assembly of the tread block are time-consuming, which indirectly affects the work efficiency.

[0004] In order to further improve the work efficiency, the utility model provides an assembled tire mold. Summary of the Utility Model

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present utility model provides an assembled tire mold, as Figures 1-3 shown, which includes an upper mold 1. A lower mold 2 for placing a tire is provided below the upper mold 1. A side plate 3 is slidably installed in the inner cavity of the upper mold 1. A pattern block 4 for machining tire patterns on the surface of the tire is installed inside the side plate 3. It further includes a limiting mechanism 5 provided on the side plate 3 and the pattern block 4; the limiting mechanism 5 includes a limiting unit and a transmission unit.

[0022] It should be noted that the limiting unit in this solution is used to provide a limiting effect for the connection between the side plate 3 and the pattern block 4; the transmission unit in this solution is used to provide a thrust for the movement of the limiting unit.

[0023] In some embodiments, the transmission unit includes a rotating rod 501, a rotating block 502, and a resisting block 503.

[0024] Specifically, the rotating rod 501 is rotatably connected to the bottom of the side plate 3, and the rotating rod 501 is used to provide support for the rotation of the rotating block 502; the rotating block 502 is fixed to the bottom end of the rotating rod 501, and the rotating block 502 is used to synchronously drive the resisting block 503 to rotate; the resisting blocks 503 are fixed to both ends of the rotating block 502, and the resisting blocks 503 are used to provide a thrust for the movement of the limiting block 505.

[0025] In some embodiments, the limiting unit includes a limiting groove 504, a limiting block 505, and a guiding ring 506.

[0026] Among them, the limiting groove 504 is opened at the bottom end of the tread block 4 and is adapted to the limiting block 505; the limiting block 505 is vertically slidably installed on the inner wall of the side plate 3 and penetrates through the side plate 3 and extends into the limiting groove 504. The limiting block 505 is used to provide limitation for the side plate 3 and the tread block 4; the guiding ring 506 is fixed on the outer wall of the limiting block 505, and the guiding ring 506 is used to provide limitation for the vertical movement of the limiting block 505.

[0027] In this embodiment, when the tread of the tire needs to be adjusted, the rotating block 502 at the bottom of the side plate 3 can be manually rotated to synchronously drive the abutting block 503 to rotate, so that the top end of the abutting block 503 no longer abuts against the bottom of the limiting block 505. At this time, the limiting block 505 moves downward along the inner cavity of the limiting groove 504 under the action of gravity. The top end of the downward-moving limiting block 505 moves out of the limiting groove 504, and the bottom end of the limiting block 505 protrudes from the bottom of the side plate 3. And under the action of the guiding ring 506, the movement of the limiting block 505 is limited, so that the limiting block 505 no longer limits the tread block 4. At this time, the tread block 4 can be taken out, and the tread block 4 with different patterns is placed in the inner cavity of the side plate 3 to complete the replacement of the tread block 4. The operation is simple, and the work efficiency is further improved.

[0028] In a further preferred embodiment of the present invention, as Figures 1-3 shown, the number of the abutting blocks 503 is two, and the two abutting blocks 503 are axially distributed at both ends of the rotating block 502 with the midpoint of the rotating rod 501 as the center; the outer wall of the abutting block 503 is inclined, and a threaded groove for the outer wall of the rotating rod 501 to rotate is formed on the inner wall of the side plate 3; a sliding groove for the vertical movement of the guiding ring 506 is formed on the inner wall of the side plate 3; the outer walls of the limiting block 505 and the guiding ring 506 are integrally in a cross-shaped structure.

[0029] In this embodiment, through this structure, when the tread block 4 is inserted into the inner cavity of the side plate 3, the power for rotating the rotating block 502 can be given, so that the abutting block 503 rotates synchronously. The top inclined surface of the synchronously rotating abutting block 503 contacts the bottom end of the limiting block 505, and at the same time, an upward thrust is given to the limiting block 505, so that the bottom end of the limiting block 505 enters the inside of the side plate 3, and the top end of the limiting block 505 enters the inside of the limiting groove 504. The two limiting blocks 505 enter synchronously to complete the movement limitation of the tread block 4.
